What did you do with your Z today V (ON TOPIC DISCUSSION ONLY)

Turns out I got the CEL again. This time i READ it. Sensor 1 in both banks, meaning I'll have to call WR and have them clean/replace them since they were fine before they replaced the cats.

Did you use an impact gun to remove the bolts to change the cats? Did you do this with the O2 sensors still installed?

I didn't remove anything. I'm sure they used an impact to remove my test pipes, but these are the primary sensors in the headers, not the secondary ones in the tp/cats.

I did hear what sounded like some cleaning going on (likely the surface where the new equipment connects to the OEM header. Now whether they left those primary sensors on while they did that or not, I don't know. Either way they'll have to foot the bill.

Chances are that the O2 sensors are shot. A lot of times when someone works on the exhaust with an impact gun. About 80% of the time. The O2 sensors get damaged. The vibrations from the gun kills the sensors. For some reason the sensors on the Z are more sensitive to vibrations then others.

Well here's to hoping they'll replace them for me without too much fuss. (thankfully I have a daily)

Not wanting to cast aspersions on the OP.. but THAT is one of 300 reasons why I don't take anything I care about to a shop if I can help it. And why I went and learned all this automotive mishigash. No one will take as much care with your car as you will. You're the only one that's doing it for free.

Good Luck with this, hope it works out. Keep us in the loop!

I talked to them today and they're convinced nothing they did (including the cleaning) would have done anything to the primary and they're saying it's a calibration issue (which no, it's pre-cat and even if there are adjustments, the car should be able to make them. plenty of cars running around here with aftermarket cats and TPs and not getting codes for the primary sensors.)

They were willing to take a look and "troubleshoot the problem" but that's where I was like no thanks. I'm not gonna get charged hourly for troubleshooting when I quite blatantly tell you there's no correlation between the front and rear O2s because the secondary sensors are disabled. I'll eventually get some new o2 Sensors (123K miles maybe it's a good idea) and I'll eventually install them. I don't need the car right now.




This is Winding Road Racing. The assumption was that they should know what they are doing, and I'll take my car to the shop based on whether it's worth my time doing it or me paying someone else to do that. Respectfully, not everyone has the ability to always do everything to the car themselves.


I should put a disclaimer saying that the previous work they did was all fine. (rescuing my Z and putting a new clutch/flywheel/cmak and repairing transmission as well as corner balancing). They're by no means a Z specialty so I have to err more to my own judgment on Z specific issues.

Very true! Always a question of time and priorities. Point I was trying to make was, two and a half years ago I was a keyboard jockey with a screwdriver, half a dozen sockets, and trouble with the concept of lefty-loosey rightie-tightie.

Now, with the invaluable help of this forum (and 1,700 hours of overtime pay) I have the tools and talent to do most things. Doesn't mean that's the path for everyone. Just want ppl to know its achievable.

And here's an image for anyone who's not familiar by now. We're talking about the sensor right near the neck of where the header meets the cat.

Installed AAM Resonated Short Tails a couple weeks ago, still trying to find the rattle noise. Going to take off some body panels this weekend....ugh.

Bought a pair of illuminated kickplates from a member and since all the other interior trim pieces in my car are black, I had the silver section wrapped in matte black.

Honestly, today I looked at my car parked in the garage and shed a tear because there is about 3-4 more months of harsh, cold, winter, here in Winnipeg, Canada. This means I still have 3-4 months before I can drive her. On Christmas day however, I installed a EVO-R CF steering wheel so that tied me over until I can drive it...
